Each C1TileViewItem has three states: minimized, maximized, and the default state (which is neither minimized nor maximized). For example, in the first image, all three of the C1TileViewItem objects in the C1TileView control appear in the default state:

In the second image, the red C1TileViewItem is maximized and the other two are minimized:

When one item is maximized, the other items are minimized and appear as specified by the MinimizedItem property. The default state uses the Columns and Rows properties to determine the layout. The minimized and maximized states use the MinimizedItemsPosition property to determine layout.
